With images taken along various sections of the almost 2,000 mile long border between Mexico and the United States, Daniel Ochoa de Olza invites the viewer to question the function and material reality of this highly politicised frontier between the two countries - 'the wall' in its natural context.

The 'Wall', much trumpeted and weaponised by US president Donald Trump , is not actually a continuous barrier between Mexico and US. Instead it consists of disparate and uneven sections of varying height and building materials with numerous gaps between them. Some sections are as short as a few metres, standing forlorn in the often inhospitable environment along the international border.
These images document this 'wall' - actually a series of fences made of steel slats varying in height between 5 and 8 metres - from up close, away from the more familiar urban settings such as Tijuana in Mexico's Baja California state, showing the arid terrain and numerous natural obstacles that have made the project so expensive and difficult to complete.

The border, at 1,954 miles, is one of the longest in the world. The barrier is often cited as one of the most expensive engineering efforts in recent history, with some sections of the wall costing up to $46 million per mile, although the average is between $20 and $25 million, depending on the terrain and other construction challenges.

So far the wall has not fulfilled its intended function. It has not stopped drug trafficking, the majority of which passes through legal entry ports. Moreover, it has singularly failed to deter migrants, both genuine asylum seekers and economic migrants. Many use a simple rope ladder to climb over the fence. The most vulnerable individuals, especially women and children, are forced to venture into extremely dangerous terrain or resort to the mafias that control sections of the wall and promise to help people across - for a price.
The fact that much of the illegal traffic across the border is now concentrated in hostile environments is the result of the so-called 'Prevention Through Deterrence' policy, introduced in the 1990s as part of U.S. immigration policy. The objective of this strategy is to tighten control in more accessible urban areas along the border, such as El Paso or San Diego, thus shifting the flow of migrants to more dangerous desert and mountain regions where extreme conditions act as a natural barrier.
This policy has been heavily criticised for causing a huge increase in the number of deaths among migrants. Since the implementation of 'Prevention through Deterrence' more than 7,800 migrants have lost their lives at the border according to the US Customs and Border Protection Office (CBP). The number of disappearances have also risen sharply, though exact figures are hard to come by. Organisations like the Missing Migrant Project and Human Rights Watch have documented hundreds of people disappearing each year while attempting to cross the border. In 2021, it estimated that at least 1,600 disappeared while trying to reach the U.S.

This section features a unique design with the wall 'floating', without a solid foundation, on the shifting sands, adapting to the constantly changing terrain shaped by the wind.
